Answer
$-3m+2$
Work Step by Step
The distributive property holds that $a(b+c)=ab+ac$ (for real numbers $a$, $b$, and $c$).
We are given the expression $-2(m+1)-(m-4)$. We can use the distributive property to simplify the terms in parentheses and combine like terms.
$-2(m+1)-(m-4)=(-2\times m)+(-2\times1)+(-1\times m)+(-1\times-4)=(-2m)+(-2)+(-m)+(4)=(-2-1)m+(-2+4)=(-3)m+(2)=-3m+2$
